I finally got "Galaxy" installed. My question is into what folder, in Galaxy, do I install my GOG games into Galaxy? I have about ten games, but Galaxy says that none are installed. The GOG games are on the same drive but not in the Galaxy folder. TX

Galaxy needs to scan for your already installed games. Click the + in the top left, then point it towards where your already installed games are. You should also go into Galaxy's options (gear icon on the bottom left) and set where you want it to install games in the future. Do not tell it to install them in Galaxy's own directory, that has caused issues in the past.
